Sony slashed its operating profit estimate by nearly 70 percent for the financial year ended March 31, saying it expects its exit from PCs to add nearly $300 million in extra costs and a weak demand for Blu-ray disc media.

The Japanese consumer electronics giant on Thursday cut its operating profit forecast to 26 billion yen ($254.53 million) from a previous estimate of 80 billion yen, adding that it would book 25 billion yen in impairment losses from its optical disc media (DVD, CD-ROM, Blu-ray) production unit for fiscal 2013 due to weak demand in Europe. Sony said that demand for physical media "contracting faster than anticipated," mainly in the European region.
